Pete of Casperelectronics.com has just published a very nice set of instructions on how to add modifications to Casio SA Series keyboards. The mods include: a fixed pitch shift that swaps the crystal, glitch knob that injects the audio from the output in to the keyboard button matrix to cause glitches, feedback potentiometer, extra button pressed switch, and a power drop via a 500 Ohm potentiometer. Also worth noting that simply crossing the crystal pins on these keyboards momentarily causes random glitches to occur. Excellent work thanks Pete.
